To all whom it may concern:

Be it known that I, CHARLES S. LABOFISH, citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Tabulating Devices for TypelVriters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains-to make and use the same.

' My invention relates to improvements in tabulating devices for typewriters, such as are used to stop the carriage at a predetermined point or points to bring the column or columns of figures into perfect alineme'nt automatically, and the objects of my invention are, first, to produce a tabulator which 1s extremely simple in construction, neat in appearance, and comprehensive in its operation; second, to roduce a tabulator which can be operated by the typewriter keys, thereby dispensing with the auxiliary set of keys or other means usually employed to accomplish the results; third, to produce simple and efficient means for effecting nunute adjustments of the tabulating or column sto 5, thereby insuring absolute accuracy; an fourth, to produce simple and efficientmeans for locking the tabulator securely when not in use, thereby preventing every ossible chance of interfering with the Workmg of the machine, by the tabulating mech- 'anism rattling loose or releasing itself and catching when the typewriter is being rapidlv operated.

fitted with mytabulating device h Fig. 8 is along1- tail transverse sectional 0 .the above and other ends which will. hereinafter appear, my invention consists of the features Of COllStlllQtlOIl, arrangements of parts and combinations of devices to be heremafter described and claimed.

I attain the objects set forth. by the construc'tion shown in the accompanying drawings, in which g Figure 1 is a plan view of the typewriter a side e1 vation of same.

tudihal ctional view through a portion of the bracket- .with the two connecting rods and one of the column stops-the parts being shown onan enlarged scale. 7 Fig. 41s a d eview of the same taken on the link 4 -4; of'Fi'g. 3. Fi s. 5 and 6 are side views of portions of t e .13 pewriter 'kevsand sections oft-he rock aft bank; J, the third, and K, the

. tends from si .lattenconstituting a portion 0 1, formed with a series of allel plane? that extend fore and aft 0 th with its rockers. Figs. 7 and 8 are fragmentary detail perspective and vertical sectional views respectively of the shift key and shifting mechanism. Figs. 9 and 10 are detail plan and transversescctional views respectively of the rock-shaft and its rockers, showing how they are shaped and graded. Fig. 11 is a vertical front to rear sectional view of one form of typewriting machine embodying my invention, the parts being shown in their normal positions. Fig. 12 is a diagrammatic side elevation illustrating a finger key depressed to actuate the tabulat ing mechanism, the type-bar being shown arrested to prevent a complete printing movement thereof.

Similar letters and figures of reference refer to similar or throughout the several views.

Referring to the drawings, A indicates the typewriter frame; B, the traveling carriageg C, the rack; D, the pinion which meshes with the rack; E is an extended release arm or lever, which by depression disengages the rack from the pinion, and releases the carriage.

F designates a guide crates with a rod G to its movement from on chine.

H indicates the first .or front bank of typewriter or printing keys; I, the second fourth bank or row of typewriter or printing keys. Each of the key levers aof the various banks of printing keys H I J and K is fulcrumed at b pipon a fulcrum bar which exe to side of the machine and each key lever is connected at 0 to a link (1 which in turn is connected at e to a crank arm 7 that projects from the heel of a type bar g, pivoted at htoa hanger 2' that is so. cured by a screw j to the top late k, the 1 the frame A of the machine; the various type bars cooperating with the platen Z and all of said piece which coopguide the carriage in to end of the ma- .parts being constructed and operating in the usual manner as in the No. 6 Remington machinefor instance, except the release lever E. To the guide piece F is secured a block steps 2, which concorresponding parts stitute's ,tabulating, or more specifically speaking, denominational stops. tact faces of these steps are in vertical The conmachine and are situated near the carriage from right to left. In other styles of typewriters which'have no guide piece the block 1 may be secured direct to any convenient part of the carriage.

Two bell-crank like 'brackets or levers 3 are pivoted to the frame A at 1 so as to rock freely; the upright arms of the said brackets being connected by a rod 5 at 6; the said rod being screwed or riveted in the brackets in order to hold them the proper distance apart, and form a unitary and rigid structure of the two brackets so that they will rock together.

Upon reference to Figs. 1 and 3, it will be seen that the extreme ends 7 of the vertical arms of the brackets or levers are enlarged to form bearings for a rod 8. This rod 8 is screw-threaded throughout its length, except at and near the ends thereof, and has a longitudinal groove 9 -in which screws 10 are seated near the endsof the rod in order to prevent it from turning in its bearings. The left-hand bearing 7 is further bored or countersunk for about one-half of its width, and a yielding collar or buffer 11, which is preferably of india rubber, but may be a metal spring ifdesired, is fitted therein and extends beyond the inner face of the bearing 7. A washer 12 is fitted securely upon the rod so as to contact with the exposed end of the buffer and leave a small space between the washer and the bearing 7 The rod 8 has a slight longitudinal movement in its bearing against the tension of the yielding collar which acts as a cushion to absorb the shock-caused by the sudden arrest of the released carriage.

Several internally screw threaded disks 13 andthumb nuts 14 are threaded upon the rod 8; a toothed washer 15 being interposed between each disk and thumb nut, which parts form column or tabulating stops. An

inwardly projecting tooth on each Washer 15 engages the groove 9 and the washer is thereby held non-rotatably upon the rod.

' The disks'13 can thus be adjusted to a nicety and locked securely by the thumb nuts against the non-rotating lock washers so that the impact of the carriage cannot dislodge or move the parts which constitute each stop. v

Beneath the front bank of typewriter keys H is a shaft 16 journaled in blocks 17 and 18, secured to the typewriter frame AL. The shaft 16 has a longitudinal movement in the blocks, and is held normally toward the left by a spring 19, which is secured in the hollow portion of the block 17 by a screw 20 and bears upon the right-hand end of the shaft 16, as shown in Fig. 1. The shaft 16 has cast integrartherewith or otherwise rigidly'secured thereto aseries of rockers 21 and a corresponding series of arresting projectionsj 2t l arms or projections of the two series being preferably set in substan- I tially V-shaped arrangement (see Figs. 9 and 10) to form two pivot bearings. The spaces 22, between the projections 21 and 24 of the different-sets, are of such a width as to admit the typewriter key levers a and permit a free vertical movement thereof and the forwardly extending projections 24; are graded or stepped in relative proportion to the graduations of the steps on the block 2, and substantially in the same direction, that is. they decrease in length from right to left, while the rearwardly extending projections 21 project to equal extents from the rockshaft and upon the opposite side thereof from the projections 2 1, so that the contact edges or faces of the projections 21 are situated in the same horizontal plane. The projections 21 are preferably slightly curved rearwardly or rounded at their free ends as at 25 in order that the key levers may have a better bearing (see Figs. 5 and 6). To the shaft 16 are secured two projecting arms 26 which are bent outwardly and are headed at their outer extremities so as to leave shanks 27 and heads 28; the shanks being in constant engagement with forked ends 29 of the brackets or levers 3.

From the foregoing description it will be seen that the rock-shaft 16 and the parts carried thereby constitute a frame which is adapted to turn on the axis of the shaft as a center to transmit a rocking motion to the brackets Sand the column stop rod carried thereby.

In the block 18 is formed a cavity 30 of a size suflicient to admit the head 28 of the arm 26 to enter freely and a vertical slot 31 is milled in the-said block and intersects the cavity 30. A sliding shift key 32 is received and moves'within the slot 31 and the.

cavity 30 and this key is provided with a cam 33 and a latch 34 and is limited in its upward movement by a plate 35 secured to the block 18. The said shift key is further fitted with a screw cap 36 and a coiled spring 37, the latter serving to hold the key in the elevated position with the cam 33 thereon in the position shown in Fig. 8 and the latch 34: engaging the head 28 on the "so that the contact faceqtif the column stop is in the same plane as he contact face of the rear-most stop 2 and the column stop is locked in its adjusted position with the thumb nut 14 bearing against the lock .Washer;15, as shown in Fig.1 The-car-.,

riage is then returned to itsnormal-positiomfi Now we will suppose that itis desired to print the amount of 10.000 underneath an amount already printed. The shift key 30 depressed; this causes the cam'33 to eject the headQS at the left-hand side of the machine from the cavity 30, at the same time shifting the shaft 16 and the parts carried thereby i toward the right just sutlicient to bring the l curved rockers 21 immediately underneath the key levers a of the first row of keys H. While pressure is still maintained on the shift key 30 the printing key bearing the numeral 5 is depressed and its lever will bear first upon the face or rearwardly eX- tending projection 21 of-the associated V- shaped rocker, causing it to incline, its inclination being limited by reason of the face or rearwardly extendingprojection 24: of the rocker touching the key lever, and arresting it 'from further downward movement, thereby preventing the type bar from com leting its printing movement, as indica ed in Fig. 12. Thisinclination of the rocker arm 21 is ietl ective to rock the shaft 16 with its arms 2, which are as stated above operatively connected to the brackets 3 to such an extent as to bring the disk 13 in the path of movement of the fifth step 2 of the block 1. The movement of the rod 5 toward the front of the machine depresses the rear end of the release arm or lever E, thereby elevating the feed rack to effect a release of the carriage, which will travel toward the left under the power of the spring drum until the fifth step '2 on the carriage (counting from right to left) meets a column stop. WVhen the pressure upon the key 5 is removed, the parts will be restored to their normal positions and it will be found that the carriage has been arrested at the fifth denominational position, when the figures 10.000 may be written and the zero representing the unit will appear .eXactly in the place where thecarriage was set and in line with the unit above it. The same operation is repeated to tabulate. the next amounts of the column, and so on, until the column is completed, when all the figures of the column or columnswill appear in perfect alinement in their respective denominational positions.

It will be observed that the moment the pressure upon the shift or tabulator con trolling key 36 and the typewriter key is removed the brackets or levers 3 return to their normal osition by gravity and the head 28 at the eft-hand side of the machine enters its cavity 30 and the latch 34: re engages the head andlocks itsecurely, therc-' .by preventing any possibility of an accidentalcontact of the disks 13 with the block b l, orthe ke levers a with. rocker arms 21 by the'ra'ttllng of .the parts or other causes during an operation of the machine.

keys therefor,

To prevent possible injury to the brackets or levers 3 by the forcible striking of the released carriage against the disks 13 carried by the brackets 3, a stop or block X is se-' 7 From the foregoing description it will be seen that the tabulating mechanism is independent of the ordinary carriage-feed mechanism and that the arrest of the carriage at the proper denominational position is not dependent upon or controlled by said mechanism.

, It is evident that numerous changes might be made in the general construction and formation of parts of my device, Without. departing from the spirit and scope of my in vention. Hence I would have it understood that I do not limit myself to exact construction, and formation of parts herein shown and described, but consider myself atliberty tomake any such alterations that fairly fall within the spirit and scope of my invention.
